CVE-2025-59706Network attack vector

Remote code execution via unvalidated API parameters

Published Mar 25, 2026 · Updated Mar 25, 2026

Improper input validation in the N2W API before 4.3.2 and in 4.4.0 allows remote attackers to execute arbitrary code. The API accepts attacker-controlled request parameters that reach a code-execution path, but the affected endpoint and downstream operation are undisclosed. No authentication or user interaction is required, and successful exploitation executes code in the N2W server context.
